Abstract

The invention relates to an injection and expansion integrated device which comprises a hollow outer pipe. An inner pipe in movable socketing connection is arranged on the outer pipe, the front end of the inner pipe is connected with an injection needle while the rear end of the same is communicated with a hollow handle, an expansion balloon is mounted outside the front end of the outer pipe in a sleeved manner, the rear end of the outer pipe is connected with a cylindrical shell, the expansion balloon is communicated with an air injection pipeline arranged in the outer pipe, and the handle is movable mounted in the shell in a sleeved manner. The injection and expansion integrated device is reasonable in design, simple in structure and convenient and safe to operate, and a submucosa tunnel can be quickly built, so that operation time is saved; risk of perforation or hemorrhage can be lowered substantially, and favorable conditions are created for improving operation quality.

Description

A kind of injection and expansion integrated apparatus
Technical field
The present invention relates to a kind of medical treatment device, a kind of by endoscopic hemostasis and expansion to form the device in tunnel under mucous membrane, specifically one injection and expansion integrated apparatus.
Background technology
In recent years, therapeutic endoscopy technology quickly grows, and endoscopic minimally-invasive operation becomes many disease of digestive tract safely and effectively treatment means.Under scope, tunneling technique is widely used in therapeutic endoscopy, and under mucous membrane, the foundation in tunnel is the follow-up basis carried out of this type of operation, is often the most incident link of complication, is the most also operation the longest time-consuming step, is therefore the committed step of operation success or failure.At present, under mucous membrane, mostly the foundation in tunnel is to be separated by submucosal injections property sharp with electric knife under scope alternately and repeatedly to carry out implementing.Although electric knife has separation fast and can the feature such as coagulation simultaneously under scope, but cutting current likely damages tunnel wall (mucous layer or bottom muscle layer), add tunnel breakage or esophageal perforation risk, therefore, need design a kind of easy to operate and safety, can quickly set up tunnel under mucous membrane, meanwhile, the therapeutic system of risk can be greatly reduced again.
Summary of the invention
It is an object of the invention to for the current difficulty run into during operation is set up in tunnel under mucous membrane, it is provided that a kind of injection and expansion integrated apparatus, easy to operate and safety, can quickly set up tunnel under mucous membrane, meanwhile, perforation or hemorrhage risk can be greatly reduced again, improve operation quality.
The technical scheme is that
A kind of injection and expansion integrated apparatus, including the outer tube of hollow, be provided with the inner tube of a pivot bush unit in described outer tube;The front end of this inner tube connects entry needle, and rear end is connected with the handle of hollow;The front end of described outer tube outside suit dilating sacculus, rear end is connected with cylinder-like shell;Described dilating sacculus is connected with the gas injecting pipe being located in outer tube;Movable being set in described shell of described handle.
Further, described dilating sacculus is circular cylindrical, it is possible to inwardly gas injection or fluid injection and expand.
Further, described gas injecting pipe is located in described outer tube wall, and is provided with gas injection interface on outer tube wall.
Further, the size of described handle inside diameter adapts with syringe nozzle, facilitates syringe to be connected with handle.
Beneficial effects of the present invention:
The present invention is reasonable in design, simple in construction, easy to operate and safety, it is possible to quickly set up tunnel under mucous membrane, saves operating time, simultaneously, moreover it is possible to perforation or hemorrhage risk are greatly reduced, and creates favorable conditions for improving operation quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Wherein: 1-entry needle;2-dilating sacculus;3-outer tube;4-gas injecting pipe;5-inner tube;6-gas injection interface;7-shell;8-handle.
Detailed description of the invention
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1.
A kind of injection and expansion integrated apparatus, including the outer tube 3 of hollow.The inner tube 5 of a pivot bush unit it is provided with, it is possible in this outer tube 3, pull and push movement in described outer tube 3.The front end of this inner tube 5 connects entry needle 1, it is possible to submucous tissue injecting fluid.The rear end of said inner tube 5 is connected with handle 8.Described handle 8 is hollow, and is connected with said inner tube 5.The size of described handle 8 internal diameter adapts with syringe nozzle, it is simple to injector head is inserted from handle 8 tail end, and injects liquid into inner tube 5.The front end of described outer tube 3 outside suit dilating sacculus 2.This dilating sacculus 2 is circular cylindrical, and is connected with gas injecting pipe 4, it is possible to by this gas injecting pipe 4 in described dilating sacculus 2 gas injection or inject liquid and be allowed to expand, and then can passivity tear submucosa.Preferably, described gas injecting pipe 4 is located in described outer tube 3 wall, and is provided with gas injection interface 6 on outer tube 3 wall, in this way it can be ensured that the periphery of outer tube 3 is circular, it is simple to walk in tissue.The rear end of described outer tube 3 is connected with cylinder-like shell 7, and makes being set in this shell 7 of described handle 8 activity, in order to handle 8 can pull and push movement along shell 7.The length of described entry needle 1 to handle 8 tail end is slightly larger than the length of outer tube 3 front end to shell 7 tail end, when making handle 8 drive inner tube 5 to move, by fully extended for entry needle 1 outer tube 3, or can take in completely in outer tube 3.
The using method of the present invention is: at direct view under endoscope, pushes handle and makes entry needle stretch out outer tube, selects to determine injection point.Syringe is connected to handle, and injecting liquid into submucosa, to fill pad loose.Then, entry needle is retracted in outer tube, another syringe is connected with gas injection interface meanwhile, and gas or liquid are injected dilating sacculus, by the expansion of dilating sacculus, passivity tear submucosa, thus reach to separate mucous layer and the purpose of muscle layer.Repeat this process, can progressively set up tunnel under mucous membrane, and, need not when injecting repeatedly adjust position, improve accuracy and described efficiency.Simultaneously as lower active dodge blood vessel position can be looked at straight during injection, carry out expanding around injection point and also can reduce tunnel internal haemorrhage risk.And carry out quick blunt separation by the expansion repeatedly of dilating sacculus, also it is prevented effectively from perforation and hemorrhage risk, totally improves surgical quality.
Part that the present invention does not relate to is the most same as the prior art maybe can use prior art to be realized.
